LOADING-MACHINE.

Specification of Letters Patent. Patented lwaw 14 j9jj Application filed January 12, 1911. Serial No. 612,176.

To all whom a t may concern:

Be it known that I, FRANK Brnnmes, a-

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, I and "useful Improvement-in Loading-Machines, of which the following is a full, clear, and exact description." I Theobject of this invention is to provide amachine adapted for use in mines, by means of which the coal or mineral which is broken from the working face or breast in the mine may be gotten out of the way, I

and loaded into the mine cars quickly and economically.

The invention consists in the novel com binations of parts, shown in the drawing,-

and hereinafter described and defined by the appended claims, which contribute "to the etficiency and practical value of said machine.

In the drawing, Figure l is a plan view and Fig. 2 a side elevation of the machine embodying the invention. Fig. 3 is a longitudinal vertical sectionalview of a part of the rocker to be ,hereinafter described and the parts supported thereby. Fig. 4 is a plan view of the wheel truck forming a part of the machine. Fig. 5 is'a transverse verti cal sectional, view through the rocker and parts carried thereby in the plane indicated by line 55 on Fig. 2. Fig. 6 is a transverse vertical sectional view on line 6 -6 of Fig. 2.

The machine includes a wheel truck-A, the wheels a and a of which are adapted to run on the mine tracks; and a superstructure supported on said truck and adapted to be moved thereon in a horizontal plane about a verticaL axis, said superstructure carrying numerous working parts to be presently explained.

The truck frame is a'built-up structure comprising side-member's a? and transverse members a Fixed to this truck are two segmental tracks a a whose center of curvature is the axis about which the super structure will swing. The ends of these tracks may be connected by side bars a.

The base of the superstructure is a'built-j up rectangular frame which includes, in

have invented a certain new the form shown, the side member 6, the

cross members 5 and supplemental longitudinal members 5 It is to be understood, however, that the particular construction of this base frame is not at all material to the invention.

There are also two transversely extended beams C, C, which are rigidly fastened to and are located below the superstructure base above described. Flanged wheels 0, 0 are mounted on these .bars 0, C, and they ride on the rails a a A reversing electric motor F which is mounted on the-truck frame is connected by a suitable train of re clucinggearing with a'sh'aft D to which a COIllOfilPlIllOTl d is fixed. This'pinion enerally in one direction or the other in a horizontal plane, and will be guided by theengagement of the flan ed wheels 0 with the tracks a a so that 1t will swing about an axis which is coincident with the axis of the two tracks a a this axis being, of course, to the rear of the truck frame and being preferably near the rear end .of the hereinafter mentioned conveyera This same motor may also be connected through a suitable train of gearing with the driving axle'a of the truck, whereby the truck may be caused to traverse the mine tracks,-and suitableclutch mechanism may be providedfor connecting'either train of mechanism with the motor. v

Secured upon-thehase frame of the superstructure are two standards E which furnish the bearing for a transverse shaft G. This shaft, in addition to its other duties, supportsthe rocker H. Two sleeves h of this rocker embrace the shaft G and lie respectively just inside of the two standards E. This rocker is rocked or tilted upon its supporting shaft so as to assume any desired angle to the horizontal by power derived fromv an electric motor J which is supported on the superstructure base. This motor, through suitable reducing gearing, drives a crank shaft K mounted in the superstructure frame. This, shaft has two crank arms .7: lined tov it and to each of these cranks a link is is pivoted, the upper end of both links being pivot-ally connected with a laterally extended bar it fixed to the rocker H.

\ The rocker in the form shown is built up of suitable angle irons and plates and has a top and two vertical sides. The rocker supports and guides the extensible hoe shank and certain counterbalances, to be presently explained. The hoe shank referred to comprises an outer tubular member M and an inner member N, which telescopes into the outer member, and has the hoe blade bl fled to its outer end. The outer member, is, for convenience, built up of channel irons in, a top plate 'm and a bottom plate m ft is supported and guided by and permitted to move longitudinally between rollers 71. 1 1. the former" being mounted on the rocker, and the latter being loose on shaft G. it has a rack m on the bottom face of the bottom plate m and this rack is engaged by a pinion p fixed to a shaft P. This shaft is mounted in bearings fined to the rocker. l't

' has a gear p at one end. and this engages the hoe shank member M.

grooves embrace longitudinally with a pinion g fired to the shaft Gr. lhis shaft has at its other end a beveled gear which meshes with a beveled pinion Q fired to the shaft of a reversing electric motor Q which is mounted on the superstructure base frame. The. inner hoe shank N at its forward end rides between and is supported and guided by rollers'qn, mounted on the hoe shank member M. Horizontal guide grooves are formed on the outer faces of the two side members of this inner hoe shank near the rear end thereof, and these extended ribs m, fixed to the inner face of the side members of the hoe shank member M. @n

the-top of the member N is a rack a and this is engaged by a pinion m which is mounted in bearings fixed to the top of On the lower face of the top member of the rocker is a rack 1 1 also engaged by the pinion m ft is evident from the foregoing that when the motor Q, is operated in one direction it will, through the described mechanism, turn the pinion g, and thereby move the cute hoe shank member hf outward or to the left, as shown in Figs. 2 and 3. lThe pinion m will, of course, gowith the member M, and will be rotated by reason of its engagement ith the fixed rack it Therefore,the inner hoe shank member N will be caused to travel outward or to the left, but at a rate twice as great as' the -rate the member travels. In other words, this inner me; her bl will more out of the outer member in as the latter moves to the left in its supports upon the'rocker. while this atevhicln is being done, or at any suitable time, the rocker is tilted so as to carry its front end downward the hoe shanks will assume the angular position indicated by dotted lines in 2. if, new, the motor Q be reversed the telescoping hoe shanks M and bl will reverse their movement, and thereby the broken @a mineral on the door of the mine will be drawn towardthe front end of the machine and up onto an apron S on the front end thereof, and thence onto a belt conveyer V of any suitable construction mounted in the base frame of the superstructure. ilhis conveyor, as shown, is of the endless belt variety. It is of familiar form, and therefore it is thought requires no special description. The driving shaft -W, therefore, is mounted on the base frame of the superstructure at the rear end thereof. and is driven by an electric motor Y mounted on said superstructure base frame two flanged track bars h. A roller 6 fixed to the associated counterweighted bar T is supported and guided by these track bars. Each counterweight has a rack t fixed to its underface, and this engages with a pinion w mounted on a stub shaft which is fined to the rocker, and the pinion /V meshes with a pinion P fined to the shaft P.
